Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 20 points:

(1,2)(3,4)(5,6,11,14,9,15,10,16)(7,17,13,8,18,20,19,12);(7,18)(10,11)(14,16)(17,20);(5,7,10,19,9,18,11,13)(6,12,14,17,15,8,16,20);(2,4)(5,8)(6,13,15,19)(7,16,18,14)(9,12)(10,20)(11,17)
